Book excerpt: From the creator of the celebrated Black Bird Yellow Sun comes another bold and beautiful concept book, this time playing with opposites and reversals. Black cat. White cat. One is long, stretching out, and the other is short, crouching. When both perch in a window, one tail is straight, the other one curly. One has an empty plate, and the other a full one. With a mouse to entertain them, variously lost and found, they move through the day, until one cat is awake and the other asleep, but for how long? With enchanting ink illustrations full of pure color, simple shapes, and an elegant use of negative and positive space, this concept board book for the youngest of readers is a joy to behold — and as graceful as a leaping cat.
